11.S8hx7g    00:05:00  00:02:00

A brave decision to play the Bishop Exchange opening. Before the game 
there were three opening scenarios discussed by the commentators. 
Moriuchi would either play Shikenbisha, the Chuza variation of the 
Yokofudori or defend against the Kakugawari (Bishop Exchange). The 
Shikenbisha seemed most likely. In the Chuza variation of the 
Yokofudori, white is expected to attack first and this is quite 
dangerous against Maruyama, who is extremely good at stopping the 
opponent's attack. The Kakugawari seemed to be even more risky, as 
Maruyama is (together with Tanigawa) the leading expert in this 
opening. In the last three years, Maruyama has had an overwhelming 
record of 14 wins against only two losses with this opening when he 
played black. Still, Moriuchi decides to meet it head on. A choice 
that was made a little bit easier by his win in the first game, but 
he must have felt that it would be hard to become Meijin if he 
couldn't beat Maruyama in his specialty.

38.P7c-7d    01:52:00  01:38:00

Diagram 1

Positive play. If black allows B*6d next, it will be hard to attack, 
so it is now or never. Still, opening the diagonal to the rook is 
risky and this is why most games continue with 38.G5b-4c followed by K2b.

39.P4f-4e    02:31:00  01:38:00
40.P4dx4e    02:31:00  02:07:00

43.B*5e!     03:04:00  03:15:00

Subtle move. Black forces the knight to 7c, allowing to play a strong 
attack later on. Black has the advantage here.

44.B*7c      03:04:00  03:18:00
45.B5ex7c+   03:05:00  03:18:00

Diagram 2

48.B*6d      03:05:00  04:09:00

The point of 43.B*5e. If white plays 48.S4d here, black has 49.S*6d 
with attack on the knight. White has no good defence against that.

49.P*4f      03:19:00  04:09:00
50.S3c-4d    03:19:00  04:09:00
51.B*6a      05:09:00  04:09:00
52.S4dx4e    05:09:00  04:38:00

In the press room 52.S*6c was expected, but Moriuchi pointed out 
after the game that 53.S*7a R8d Bx5b+ Sx5b S6b+ is good for black.

53.P2e-2d    05:12:00  04:38:00
54.P2cx2d    05:12:00  04:40:00

60.S4ex4f    05:12:00  04:42:00
61.G4g-5f    05:13:00  04:42:00

61.G4h or 61.Gx4f also look good for black. Still, 61.G5f is not a 
bad move.

62.B*3g      05:13:00  05:33:00
63.R2h-1h?   06:09:00  05:33:00

Diagram 3

This is an important mistake which turns the tables. As Habu pointed 
out 63.Rx2d P*2c R2g Bx1i+ Gx7c L*2d P*2e +B1h Px2d +Bx2g Gx4f R*4i 
K8h Rx4f+ L*2i would have been good for black as white can't move 
the promoted bishop without allowing Px2c+.

81.R4dx6d    07:12:00  06:44:00
82.G*7a!     07:12:00  06:45:00

Diagram 4

Good move. This not only defends against the rook promotion on 6b, 
it also aims at capturing the rook. The more natural looking 82.G*5a 
would be answered with 82.R6c+ and it is almost impossible to kill 
the dragon.

83.B*4f!?    07:38:00  06:45:00

83.R6c+ fails to S*7b +Rx7d G*6c, and both 83.B*6b G*5d R6c+ S*7b 
+Rx5d Gx6b and 83.B*8b Gx8b R6b+ S*5b +Rx8b B*9c are also winning 
for white, so most commentators thought the game would be over soon 
here. 83.B4f is a very hard move to play, as this is black's final 
piece and using a major piece for a drop outside the enemy camp 
seems to be a terrible waste. However, it is a tribute to Maruyama's 
strength that he still plays this brave move, which is the only way 
to try and hang in there.

97.R7d-8d    08:31:00  08:17:00
98.G*9c?     08:31:00  08:28:00

Diagram 5

By carefully filling all the holes in his camp with piece drops, 
Moriuchi has built a winning position. However, 98.G*9c is a mistake. 
White would have won quickly after 98.G*7d R8c+ P*8b.

99.P*4d      08:33:00  08:28:00
100.S4c-3b   08:33:00  08:29:00
101.R8d-6d   08:33:00  08:29:00
102.G7a-6b   08:33:00  08:33:00
103.P*2e     08:39:00  08:33:00
104.S6cx6d   08:39:00  08:38:00
105.B3gx6d   08:42:00  08:38:00
106.R*3i?    08:42:00  08:38:00

Better was the simple 106.S4d.

107.P2ex2d   08:44:00  08:38:00
108.P*2g     08:44:00  08:39:00
109.R2h-5h   08:46:00  08:39:00
110.S3cx4d   08:46:00  08:39:00
111.P2d-2c+  08:48:00  08:39:00
112.S3bx2c   08:48:00  08:41:00
113.P*2b     08:48:00  08:41:00
114.G6b-6c   08:48:00  08:44:00
115.B6d-7e   08:48:00  08:44:00
116.P*8e     08:48:00  08:46:00
117.P*5i     08:50:00  08:46:00
118.P8ex8f   08:50:00  08:46:00
119.S7gx8f   08:50:00  08:46:00
120.N*8c     08:50:00  08:48:00
121.B7ex9c+  08:51:00  08:48:00
122.L9ax9c   08:51:00  08:49:00
123.P2bx2a+  08:51:00  08:49:00

With this promoted pawn near the king, black suddenly has good chances 
for attack. It can be called only luck that white still has a way to 
win in this position.

124.B*5e     08:51:00  08:49:00
125.K8h-9h   08:51:00  08:49:00

136.P8ex8f   08:54:00  08:56:00
137.G8gx8f   08:54:00  08:56:00
138.L*9g!    08:54:00  08:56:00

Diagram 6

Moriuchi must have been very happy that he found this move, which is 
the only way for white to win. Simply 138.Px9f G4d S*9g Nx9g Px9g+ K8i 
N*7g K7i is winning for black. Without a pawn drop on the 7th file, 
white has no way to get to the king.

139.K9h-8h   08:54:00  08:56:00

No choice. After 139.Nx9g or 139.Kx9g, the white attack gains decisive 
speed after 140.Px9f.

Final Diagram

White wins after both 165.K8g Rx6h+ or 165.K7i +L8i Kx8i Rx6h+. A huge 
win for Moriuchi, who now defeated Maruyama in his two favourite 
openings. Still, in this second game it was not Maruyama's opening 
that was the cause for his defeat, so if he is able to win game three, 
it will still be Moriuchi who has to come up with something new in 
game 4. Maruyama has a very important game coming up. Going 3-0 down 
will almost certainly mean the loss of his Meijin title...
